Objective: To explore the efficacy and safety of position selection in combination with intra-pleural thrombin injection in the treatment of persistent air leakage (PAL) after medical thoracoscopic treatment of bullous pulmonary-pleural diseases (e.g. spontaneous pneumothorax or giant emphysematous bulla). Methods: This was a prospective study conducted in Rizhao Hospital of Traditional Chinese Medicine from August 2018 to November 2020. Twenty patients(19 males,1 female) with a mean age of (62.3±8.1) years met the diagnostic criteria for PAL which was defined as the air leak persisted more than 3 days despite of the closed thoracic drainage after medical thoracoscopic treatment of bullous pulmonary-pleural diseases.They received the following treatment procedures (referred to as "position plus"):①Pleural cavity injection (50% glucose 20 ml+thrombin 5 000 U).②Changing the patient's position under continuous negative pressure suction to find the position causing the complete stop or significant reduction of air leakage, and keeping in the position for 24-48 hours.③If the PAL wasn't stopped 48 hours later, the procedures above would be repeated.The duration of air leakage after "position plus", times of pleural cavity injection, condition of lung re-expansion, recurrence of air leakage and complications during hospitalization were recorded. Descriptive statistics were used to summarize the results: ¯x±s or M ( P 25 , P 75 ) for continuous variables; frequency and percentages for categoric variables. Results: A total of 20 patients were included. The average duration of air leakage after"position plus" was (1.32±0.97) days. The times of pleural cavity injection required were 1.0(1.0, 1.0).All the patients showed good lung re-expansion in review of imaging after PAL was stopped. One patient had recurrent air leakage during hospitalization. No serious complications occurred. Conclusion: The comprehensive "position plus" intervention method is effective, safe and easily operating for the treatment of PAL after medical thoracoscopic treatment of bullous pulmonary-pleural diseases.

Background: Bronchial sleeve lobectomy is essential surgical approach to treat centralized lung cancer. It is the best reflected the principle of lung cancer surgery, "remove tumor completely while minimize pulmonary function loss". Bronchial pleural fistula (BPF) is not common but very severe complication of bronchial sleeve lobectomy, that is usually fatal. Present article is to explore clinical effect on prevention of bronchial pleural fistula (BPF) in bronchial sleeve lobectomy, by wrapping brachial anastomosis with pedicled pericardial fat flap., Methods: Clinical data of 39 non-small cell lung cancer (NSCLC) patients who underwent surgical resection during January 2016 to May 2019 in Lung Cancer Center of West China Hospital, Sichuan University were collected and retrospectively analyzed. All of the patients underwent bronchial sleeve lobectomy and a brachial anastomosis wrapping with pedicled pericardial fat flap., Results: All patients recovered well and were discharged within 6 d-14 d after operation. No BPF occurred, nor other severe complications, such as reoperation needing intrathoracic bleeding, several pneumonia and respiratory failure, and life threatening cardiac arrhythmia. Only one patient (1/39) had several anastomotic stenosis and consequential atelectasis of residual lung in operative side 6 months after surgery., Conclusions: Wrapping bronchial anastomosis with pedicled pericardial fat flap in bronchial lobectomy for centralized NSCLC is a simple and effective approach to prevent BPF, thus safety of the operation could be significantly improved.

Background: Bronchial pleural fistula (BPF) is a common complication after thoracic surgery for lung resection. Clinical treatment is complex and the effect is poor. The treatment of BPF after lung resection has plagued thoracic surgeons. We reviewed retrospectively the clinical and follow-up data of 6 patients in our hospital who underwent the omentum transplantation in thorax to cover bronchial stump as treatment of BPF after pulmonary resection to analyze why BPF occurs and describe this treatment method. We intend to discuss and evaluate the feasibility, safety and small sample success rate ofthis treatment method., Methods: During August 2016 to February 2018, six patients in our hospital underwent remedial open thoracotomy and omentum transplantation in pleura space to cover bronchial stump as treatment of bronchopleural fistula after pulmonary resection. Four patients had undergone a prior pneumonectomy and two patients had undergone a prior lobectomy (the residual lungs were resected with the main bronchus cut by endoscopic stapler during the reoperation). The bronchial stumps were sutured by 4-0 string with needle and covered by omentums, which were transplanted in pleura space from the cardiophrenic angle. Postoperatively, the pleura space was irrigated and drained. Summarize the clinical effect and technique learning points., Results: The patients were all males, aged 61 to 73 years (median age: 66). BPF occurred from postoperative day 10 to 45 (median postoperative day 25). The reoperation was finished in 80 mins-150 mins (median 110 mins). Total blood loss was 200 mL-1,000 mL (median 450 mL). These patients were discharged on postoperative day 12-17 (median 14 days), and there was no more complications associated with bronchopleural fistula. All six patients' bronchial stumps were well closed (100%) and have recovered well during the follow-up period, which lasted 1 month-18 months., Conclusions: Remedial operation should be performed as soon as possible when BPF after pulmonary resection diagnosed. Excellent prognoses can be achieved by omentum which is easy to get transplanted in thorax to cover bronchial stump as treatment in patients with BPF after pulmonary resection those who can tolerate reoperation.

Objective: To investigate the clinicopathological characteristics and prognosis of malignant pleural mesothelioma., Methods: Thirty patients with malignant pleural mesothelioma diagnosed between January 2006 and June 2012 in our hospital were studied retrospectively. Clinical manifestations, radiological characteristics, endoscopic features, histopathology, and survival status were analyzed., Results: There were 15 males and 15 females, with a median age of 58 years. The commonest clinical symptoms were dyspnea on exertion (26 cases), followed by chest pain (15 cases). The main radiological manifestations were small to large amount of pleural effusions (28 cases), often accompanied by pleural thickening and/or pleural nodules.Of the 30 cases, 25 were diagnosed through medical thoracoscopy and 1 through surgical thoracoscopy. Thoracic lesions manifested as nodules of diffuse distribution on the diaphragmatic pleura and parietal pleura.Some pleural surface was covered with lesions like white tiles.Histopathological examination showed epithelial type in 24 cases, sarcomatoid type in 5 and biphasic type in 1 case.Immonohistological examination showed that the positive rates of calretinin, MC, D2∼40 were 27, 25 and 19 cases respectively.Fifteen patients received chemotherapy, 2 underwent pleurectomy, and 8 were treated with best supportive care. Twenty-four patients were followed for 1 month to 6 years, and 6 patients were lost.Overall survival time was 1-54 months. Those who survived longer than 24 months received chemotherapy with pemetrexed and cisplatin/carboplatin or pleurectomy., Conclusions: Clinical manifestations of malignant pleural mesotheliome were nonspecific, medical thoracoscopy can make early diagnosis. The pathological diagnosis of malignant pleural mesothelioma was based on immunohistochemical examination, calretinin, MC and D2-40 had positive diagnostic value. Malignant pleural mesothelioma had poor prognosis, chemotherapy with pemetrexed and cisplatin/carboplatin could prolong the survival time of the patients.

Objective: To investigate the method of early surgical treatment of bronchopleural fistula after pneumonectomy., Methods: Twelve patients (9 males and 3 females with a mean age of 58.6-/+5.7 years) with bronchopleural fistula after pneumonectomy received a reoperation within 72 h after a definite diagnosis. Empyema was found in none of the 12 cases. Fistula occurred within 4 to 17 days (8 days in average) after the operation. The fistula of the residual main bronchus was resected, and the thoracic cavity was asepticized by flushing., Results: Ten patients were discharged with complete healing. One patient was discharged following open drainage with daily change of the wound dress. One patient died due to multiple organ failure. The hospital stay of the patients ranged from 18 to 49 days (31 days in average) after the reoperation., Conclusion: Bronchopleural fistula after pneumonectomy, in case that empyema and multiple organ failure do not occur, can be healed by closing the fistula with the stapling device in early stage. Flushing the thoracic cavity is also necessary after the reoperation.

Objective: To evaluate the therapeutic effect of remaining integrated mediastinal pleura upon the aortic arch and performing the anastomosis at the left cervix in radical operation for esophageal carcinoma., Methods: Ninety-eight patients with esophageal carcinoma were treated with the operation mentioned above. Among them, 56 patients had cancer in the middle, 12 in the upper-middle, 24 in the lower-middle segments, and 6 had double-primary tumors, with carcinoma length of (5.2+/- 2.4) cm. The TNM stages were 6 of Stage I and 92 of Stages II-III. All cases were squamous cell carcinomas., Results: All patients had satisfactory operation processes, without perioperative death, chylothorax, dyspnea, gastric retention, incision infection, and severe gastro-esophageal reflux. The life quality of the patients was improved., Conclusion: The radical operation with remaining integrated mediastimal pleura upon the aortic arch and anastomosis at the cervix for treating esophageal carcinomas is of minimal invasion with fewer complications, and may be used in clinical practice.

Objective: To evaluate the effects of limited pleuro-pneumonectomy for bronchogenic carcinoma associated with cancerous pleural effusion., Methods: From January. 1994 to December 1997 we performed limited pulmonary lobectomy wedge resection of lung, resection of the metastases of the parietal pleura, visceral pleura, diaphragmatic pleura and pericardiac pleura, and electro incision of the micormetastases of the above position as well as cleaning the mediastinal lymph nodes in 14 cases., Results: The 14 cases were followed-up to December 1998. Eight patients of them died, the other 6 patients survived with a survival period of 7 - 30 months (median survival period 16.5 months). No pleural effusions recurrence was seen. The longest survival period was 30 months. There were no operative mortality and no severe postoperative complication. Chest distress, dyspnea and pain of chest or abdomen were relieved., Conclusions: This simple method has such advantages as, less traumatic, rapid rehabilitation and effective control of pleural effusion. The postoperative survival period is longer than that of palliative operation and medical therapy. The pain caused by parietal pleural metastasis can be relieved.

70 patients with spontaneous pneumothorax were treated surgically. They were cured without complications. The recurrence rate was 1.2%. The authors stressed the timely surgically treatment of spontaneous pneumothorax and suggested suture-ligature and incision-suture of lung bulla. Pulmonectomy should be avoided, while parietal pleura denudation, and chemical cauterization are used to prevent recurrence. Two patients with bilateral spontaneous pneumothorax operated successfully were described in detail.

The article reported the use of a modified technique in the treatment of chronic empyema by decorticating only the visceral fibrous plate and leaving the parietal fibrous plate undecorticated. The cure rate was 100% and mortality rate 0%. This modified decortication has the advantages of simplifying the operative procedure shortening the operation time, lessening bleeding, and reducing operative trauma and risk. This modified technique may be applicable in most cases of chronic empyema.

Sixty-five cases of chylothorax treated at the Shanghai Chest Hospital over the past 30 years are reviewed. The causes of chylothorax in this series were mainly traumatic and postoperative (47/65). Two cases were associated with chylopericardium and another 2 with chylous sputum. The authors believe that untreated chylothorax is a serious, often life-threatening entity and that the following principles are applicable in its management: (1) If daily chyle loss exceeds 1000 ml in adults with no tendency of subsidence, surgery is indicated especially in the effusion may lead to disastrous nutritional and immunologic consequences; (2) Ligation of the thoracic duct is effective by a mass ligature encircling all tissues between the azygos vein and the aorta. The most favorable site for ligation is immediately above the diaphragm. Over dissection of the thoracic duct should be avoided; (3) The proper surgical approach is on the side of the effusion in unilateral chylothorax, but right side approach is preferred in case of bilateral chylothorax or when the origin of chylous fistula is unknown; (4) Pleurodesis is indicated for those cases if the duct is not obviously present or chyle comes from the pleural lymphatics. Concentrated glucose solution with or without Talc suspension is recommendable.
